GA: but here in the UK we have the perfect punishment for animals which kill without explanation: it's called fox hunting! Of course, there IS an explanation for all human activities, even when it's dressed up as genius when someone like Oppenheimer invents the hydrogen bomb, Gatling inventing a gun which will mow down hundreds more enemy troops at one sitting, or Colt inventing the very clever revolver, allowing a gun's chamber to empty more bullets more quickly into its shooter's victim. The world of invention is full of men who created all of the ways of killing more and more humans, and not one of them went to jail (solitary or otherwise) for it. No, they were usually rewarded with well-paid jobs and pensions, or wealth from their patents.
We get excited by the actions of killers (serial, spree, mass, assassin or terrorist) because we think they represent something abnormal in society, which they don't. Human intelligence is as likely to produce the 'genius' of Oppenheimer, at the same time that it produces the likes of Edison, Brunel, Otis, and so many more who've made billions of lives easier and more fruitful.
In other words, murdering takes many different forms, much sanctioned and encouraged by the State (and previously by the Church and its Kingdom), or individual - all by the random chance of one person's brain function over another's. When a woman produces a baby, she may be producing the world's next great medical saviour as equally as she may be producing the world's next worst despot.
